Product Introduction
The Bently Nevada Velomitor CT Velocity Transducer (Model: 190501-12-00-02) is a compact, rugged vibration sensor designed to measure absolute bearing vibration in industrial machinery. Unlike proximity probes that monitor shaft movement, the Velomitor CT focuses on casing vibration, making it particularly effective for applications where shaft access is limited or unnecessary.
This sensor integrates velocity measurement technology with a robust mechanical structure, providing reliable output across a wide range of operating conditions. It is widely used in rotating equipment such as motors, pumps, fans, and compressors, where consistent vibration monitoring is essential for early fault detection.
With its integrated cable design and industrial-grade sealing, the Velomitor CT ensures stable signal transmission even in harsh environments. Its compact size and simple installation make it a practical choice for both new installations and retrofit projects.

FAQ
- What type of vibration does the Velomitor CT measure?
It measures absolute vibration velocity of the machine casing, which reflects the overall dynamic behavior of the equipment rather than shaft movement. - How does a velocity transducer differ from an accelerometer?
A velocity transducer outputs a signal proportional to vibration velocity, which is often more directly related to machine damage energy, while accelerometers measure acceleration and may require integration. - Where should the sensor be installed on the machine?
It is typically mounted on the bearing housing or solid structural points where vibration transmission is most representative of machine condition. - Is this sensor suitable for low-speed machinery?
Yes, it performs well in low to medium-speed applications, particularly where velocity measurement provides better diagnostic value than acceleration. - What factors can affect measurement accuracy?
Mounting quality, surface condition, temperature variation, and cable integrity can all influence signal accuracy. - Does the sensor require external signal conditioning?
Depending on the monitoring system, additional signal conditioning or interfacing modules may be used to process the output signal. - Can the sensor operate in harsh environments?
Yes, it is designed with sealed construction and durable materials to withstand industrial conditions such as dust, oil, and moisture. - How does mounting method impact performance?
Rigid mounting, such as stud mounting, provides better frequency response and accuracy compared to adhesive methods. - What is the typical output signal type?
It provides a voltage signal proportional to vibration velocity, which can be directly used by monitoring systems. - What are common issues during operation?
Loose mounting, damaged cables, and environmental interference are the most common causes of unstable or inaccurate readings.
